Title: NEURAL NETWORK COMPUTATION APPARATUS AND METHOD
Abstract:
A neural network computation apparatus and method. The neural network computation apparatus comprises: a control unit (100), a storage unit (200), a sparse selection unit (300), and a neural network computation unit (400); the control unit (100) is used for producing micro-commands respectively corresponding to each unit, and sending the micro-commands to each corresponding unit; the sparse selection unit (300) is used for selecting neural network data corresponding to an effective weighted value for computation from the neural network data stored in the storage unit (200) on the basis of the micro-command corresponding to the sparse selection unit (300) issued by the control unit (100) and according to position information indicated by the sparse data therein; and the neural network computation unit (400) is used for executing neural network computation on the neural network data selected by the sparse selection unit (300) on the basis of the micro-command corresponding to the neural network computation unit (400) issued by the control unit (100), in order to obtain computation results. The present apparatus and method improve the ability of the neural network computation apparatus to process different types of data, increasing the speed of neural network computation whilst reducing power consumption.
